Thanks Oytis for your detailed reply!You can do much better than this with a DBX and a low engineering effort.
You can plot 10.000ly legs,selecting Fastest Route,meaning three plots to get there
If this scares you...you're probably playing the wrong game or should not bother with Exploration
Make it quicker Using Neutron to boost your FSD (you have to take an AFMU to heal the damage after a while) or embark on a Taxi (FC)
FSD Injection is meant for other purposes,anyway level 1 adds 25% at your jump range,Level 2 50%,Level 3 100%,meaning the higher your normal jump range is,the bigger improvement with FSD Injection.
I don't know how much I can improve FDS range. Ten maybe? I travel with engineered-FSD, often with no shields and some empty modules as well to reduce weight. Sure it can be better but won't be really revolutionary I suppose. Perhaps I am wrong.
About distances: It's not a matter of scare cmdr, but you know I played original Elite many many years ago. I've already done this.
The game was no-frills, basically the pleasure of exploration (none could tell where or what to do).
But I was a kid with loads of time to lose my self in space just doing nothing. (sigh)
Now pleasure is the same. Can't say the same for time. And if I dedicate few hours only to hear "frame shift drive charging" without getting the destination, you know, pretty pointless. Too much is too much (I mean, unless you have loads of time) even though I love what FD have done.
